Description

TECHNICAL FIELD

[0001] The utility model belongs to clinical health care product field especially, it relates to a new type of bed patient prevents lower limb venous thrombosis device. BACKGROUND

[0002] Long-term bed is the risk factor of lower limb venous thrombosis, and the patient may suffer from pulmonary embolism and other complications, endangering the life of the patient. Once the thrombus occurs, the patient needs to be treated by interventional surgery, anticoagulation, etc., which will increase the treatment, medication, hospitalization cost and hospitalization length of the patient. Therefore, it is very important to prevent lower limb venous thrombosis. For patients with certain activity ability, early active exercise is the recommended method for preventing venous thrombosis in guidelines. Ankle pump exercise is divided into flexion and extension exercise and circular motion. The intermittent contraction and relaxation of the calf muscle group during exercise can increase the venous blood flow rate and prevent the formation of lower limb venous thrombosis. For patients with poor muscle strength and unable to actively move, passive exercise also has a certain effect on preventing lower limb venous thrombosis. The pressure pump increases the venous blood flow rate of the patient and prevents blood coagulation during the intermittent pneumatic repeated compression process, thereby helping to prevent deep venous thrombosis and pulmonary embolism. There is no perfect device on the market that can help patients complete ankle pump exercise, which is the starting point of this patent design.

[0031] Working principle:

[0032] Adjustment of the working principle of the circumferential movement assembly

[0033] Simulation of dorsiflexion and toe flexion movements

[0034] The cam motor in the circumferential movement assembly, under program control, not only performs forward and reverse rotation to drive the foot positioning soft groove to rotate clockwise and counterclockwise, but also, through specific cam curve design, causes the foot positioning soft groove to produce periodic angular changes during rotation, thereby simulating the dorsiflexion and toe flexion movements of the human ankle joint. When the cam motor rotates, power is transmitted through the universal joint, causing the foot positioning soft groove to move along a predetermined trajectory. For example, within one movement cycle, the foot positioning soft groove first slowly dorsiflexes the patient's foot, maintaining a certain angle (e.g., 20°-30°) for a short period of time, then slowly toe flexes, maintaining a certain angle (e.g., 30°-40°) again, and so on. This simulated dorsiflexion and toe flexion movement can more comprehensively activate the calf muscle groups, including the soleus and gastrocnemius muscles, promoting more effective muscle contraction and relaxation and further increasing venous blood flow.

[0035] Coordination with other movements

[0036] Dorsiflexion and toe flexion movements are interwoven with rotational movements during rotation, forming a more complex and natural human movement pattern. For example, dorsiflexion movements begin when the foot positioning soft groove rotates clockwise to a specific position, then continues to rotate and transitions to toe flexion movements, and the same occurs counterclockwise. Such coordinated movements can better promote the calf muscle pump effect, allowing blood to more smoothly return in the veins and improving the effect of preventing thrombosis.

[0037] Optimization of the overall coordination working principle

[0038] Coordination with the inflation assembly

[0039] The air pump of the inflation assembly works intermittently in coordination with the dorsiflexion and toe flexion movements and the rotational movements of the circumferential movement assembly. When the foot positioning soft groove drives the foot to perform dorsiflexion and toe flexion movements and rotational movements, the inflatable foot sleeve exerts intermittent pressure on the lower limbs under the periodic inflation and deflation of the air bag. During dorsiflexion, the inflatable foot sleeve appropriately increases the pressure to help push the blood back from the lower limb veins; during toe flexion, the pressure can be adjusted according to the situation to adapt to the physiological characteristics of venous return. For example, the air pump can start to inflate when the dorsiflexion movement reaches its peak, causing the pressure to gradually increase, maintaining a certain pressure or slowly deflating during toe flexion, forming a dynamic pressure change that coordinates with muscle movement to promote blood flow and prevent blood clotting.

[0040] Coordination with the vibration assembly

[0041] The vibration generated by the vibration assembly continues to work when the movement assembly performs the dorsiflexion and plantarflexion movement and the inflation assembly works. The vibration frequency and amplitude can be adjusted according to the patient's tolerance and treatment needs. When the dorsiflexion and plantarflexion movement of the foot is performed, the vibration can better stimulate the blood circulation of the foot and calf, and enhance the effect of muscle contraction. For example, the vibration frequency is adjusted between 20-50Hz, and when the dorsiflexion movement is performed, the vibration amplitude can be appropriately increased (such as 3-5mm) to promote faster blood return; when plantarflexion is performed, the vibration amplitude can be slightly reduced (such as 1-3mm) to maintain the promotion effect of blood circulation and further improve the overall effect of preventing thrombosis. For 1-5mm. Patients can adjust it to a comfortable state according to their own feelings under the guidance of medical staff.

[0042] Mode selection

[0043] A special mode selection button is set on the controller, and the patient or medical staff can select a simple rotation movement mode, a dorsiflexion and plantarflexion movement mode, or a mixed mode combining the two according to the specific situation of the patient. For patients who have just undergone surgery or are physically weak, they can first choose a simple rotation movement mode, and then try a mixed mode after their body adapts; while for patients in good physical condition who need more active prevention of thrombosis, they can directly choose a mixed mode.

[0044] Parameter setting

[0045] For dorsiflexion and plantarflexion movements, corresponding parameter setting options are added. For example, the dorsiflexion angle range can be set to 20°-30°, the plantarflexion angle range to 30°-40°, and the movement speed (i.e. the number of dorsiflexion and plantarflexion cycles completed per minute) can be adjusted between 5-10 times. At the same time, adjust the coordination parameters of the inflation assembly and the dorsiflexion and plantarflexion movement, such as the increase rate of the air pump inflation pressure at the beginning of the dorsiflexion movement, the pressure holding or release parameters during plantarflexion, etc. The parameters of the vibration assembly can also be optimized according to the dorsiflexion and plantarflexion movement, such as increasing the vibration frequency to 30-50Hz during dorsiflexion and reducing it to 20-30Hz during plantarflexion, to better adapt to the promotion needs of blood circulation in different movement stages.

[0046] Patient use precautions

[0047] Initial adaptation and monitoring

[0048] When the patient first uses the device for increasing dorsiflexion and plantar flexion movement, the patient needs to be closely observed by medical staff. The medical staff should check whether the patient's foot is properly placed in the soft groove of the foot positioning device and ensure that there is no discomfort or slipping during the dorsiflexion and plantar flexion movement. At the same time, the medical staff should monitor the patient's heart rate, blood pressure and other vital signs, and observe the patient's tolerance to the new movement mode. If the patient experiences pain, dizziness or other discomfort during use, the use should be stopped immediately and the parameters or mode should be adjusted.

[0049] Regular evaluation and adjustment

[0050] The medical staff should regularly evaluate the effect of the device on the patient after use, including the swelling of the lower extremities, changes in blood flow rate (which can be monitored by relevant detection equipment), etc. According to the evaluation results, the parameters of dorsiflexion and plantar flexion movement, the movement mode and the parameters of the inflation and vibration components should be adjusted in a timely manner. For example, if it is found that the swelling of the patient's lower extremities has not improved significantly, the movement amplitude or frequency of dorsiflexion and plantar flexion can be appropriately increased, and the inflation pressure and vibration intensity can be adjusted to improve the effect of preventing thrombosis. In addition, the use plan of the device should also be adjusted in a timely manner according to the changes in the patient's condition, such as postoperative recovery, changes in physical activity ability, etc.

[0051] The above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions also belong to the scope of the present application, and the patent protection scope of the present application should be defined by the claims.
